Japanese-born artist Takashi Horisaki used to live in New Orleans. He recently returned to the Lower 9th Ward to bring attention to the city’s continuing struggle the best way he knew how: by making a sculpture. It's based on a wind- and water-ravaged shotgun house. Before its demolition in mid-July, the sculptor painstakingly cast the house in latex and trucked the panels to a sculpture park in New York City. We sent two reporters to track the house as it moved north. Jason Rhein was on the ground in New Orleans. WNYC's Jocelyn Gonzales picked up the trail in New York.
